请求按照要求编写一个脚本

要求写2个shell
需求功能：对比lz4和lzbench的压缩性能（需要log压缩速度和解压缩速度，一共4个数据）
测试heartbeat在被hang住了以后3-4s能否正常恢复工作
没有思路，求指点

1.测试lz4性能：

#!/bin/bash

# Test lz4 compression performance

echo "Testing lz4 compression performance..."

# Compress test data with lz4
start_compress_time=$(date +%s)
lz4 -f test_data test_data.lz4
compress_duration=$(($(date +%s) - $start_compress_time))

# Decompress test data with lz4
start_decompress_time=$(date +%s)
lz4 -df test_data.lz4 test_data_decompressed
decompress_duration=$(($(date +%s) - $start_decompress_time))

# Log results
echo "lz4 compression time: $compress_duration seconds"
echo "lz4 decompression time: $decompress_duration seconds"

2.测试lzbench性能：

#!/bin/bash

# Test lzbench compression performance

echo "Testing lzbench compression performance..."

# Compress test data with lzbench
start_compress_time=$(date +%s)
./lzbench -1 -T test_data > test_data.lzbench
compress_duration=$(($(date +%s) - $start_compress_time))

# Decompress test data with lzbench
start_decompress_time=$(date +%s)
./lzbench -d test_data.lzbench > test_data_decompressed
decompress_duration=$(($(date +%s) - $start_decompress_time))

# Log results
echo "lzbench compression time: $compress_duration seconds"
echo "lzbench decompression time: $decompress_duration seconds"

3.测试heartbeat的shell脚本：

#!/bin/bash

# Test Heartbeat recovery after hang

echo "Testing Heartbeat recovery after hang..."

# Start Heartbeat process
./heartbeat &
heartbeat_pid=$!

# Hang Heartbeat for 3-4 seconds
sleep 3
kill -STOP $heartbeat_pid
sleep 1
kill -CONT $heartbeat_pid

# Check if Heartbeat has recovered
if ps -p $heartbeat_pid > /dev/null
then
  echo "Heartbeat has recovered."
else
  echo "Heartbeat has not recovered."
fi

请注意，这些脚本可能需要进行一些调整以适应您的环境和需求

对比lz4和lzbench的压缩性能：
shell 1

#! /bin/bash

# Test lz4 compression performance

for file in <list-of-test-files>; do
  echo "Testing lz4 compression performance for file $file"
  lz4 -f $file $file.lz4
  echo "Compression time: $(date +%s.%N) - $(stat -c %Y $file.lz4)" | bc
  lz4 -d $file.lz4 $file.uncompressed
  echo "Decompression time: $(date +%s.%N) - $(stat -c %Y $file.uncompressed)" | bc
done | tee lz4-compression-performance.log

shell 2:

#! /bin/bash

# Test lzbench compression performance

for file in <list-of-test-files>; do
  echo "Testing lzbench compression performance for file $file"
  lzbench -b $file
  echo "Compression time: $(date +%s.%N) - $(stat -c %Y $file.lzbench)" | bc
  lzbench -d $file.lzbench
  echo "Decompression time: $(date +%s.%N) - $(stat -c %Y $file.uncompressed)" | bc
done | tee lzbench-compression-performance.log

测试heartbeat在被hang住以后3-4s能否正常恢复工作：

#! /bin/bash

# Test heartbeat recovery after hang

while true; do
  echo "Testing heartbeat recovery after hang"
  <start-heartbeat>
  sleep 3
  <hang-heartbeat>
  sleep 4
  <unhang-heartbeat>
  echo "Heartbeat recovery time: $(date +%s.%N) - $(stat -c %Y heartbeat-recovery.log)" | bc
done | tee heartbeat-recovery.log

1.对比性能

```bash
#!/bin/bash

# Test lz4 compression performance
echo "Testing lz4 compression performance"
lz4 -t file.in file.lz4
echo "lz4 compression time: $(date +%s.%N --reference=file.in)"

# Test lzbench compression performance
echo "Testing lzbench compression performance"
lzbench -t file.in
echo "lzbench compression time: $(date +%s.%N --reference=file.in)"

# Test lz4 decompression performance
echo "Testing lz4 decompression performance"
lz4 -d file.lz4 file.out
echo "lz4 decompression time: $(date +%s.%N --reference=file.out)"

# Test lzbench decompression performance
echo "Testing lzbench decompression performance"
lzbench -d file.lz4
echo "lzbench decompression time: $(date +%s.%N --reference=file.out)"

2.被hang住后如何测试回复性能：

#!/bin/bash

# Start heartbeat process
./heartbeat &
pid=$!

# Hang the process for 3-4 seconds
sleep 3
kill -STOP $pid
sleep 1
kill -CONT $pid

# Check if the process has recovered
if ps -p $pid > /dev/null
then
  echo "heartbeat has recovered"
else
  echo "heartbeat has not recovered"
fi

```

对比 lz4 和 lzbench 压缩性能的 shell:

#!/bin/bash

# 创建日志文件
log_file=lz4_lzbench_comparison.log
echo "Filename,lz4 Compress Time,lz4 Decompress Time,lzbench Compress Time,lzbench Decompress Time" > $log_file

# 测试数据
test_data=(test1 test2 test3 test4)

# 循环访问测试数据
for file in "${test_data[@]}"; do
  # Compress with lz4
  start=$(date +%s.%N)
  lz4 -z $file $file.lz4
  end=$(date +%s.%N)
  lz4_compress_time=$(echo "$end - $start" | bc)

  # 用 lz4 解压
  start=$(date +%s.%N)
  lz4 -d $file.lz4 $file.decompressed
  end=$(date +%s.%N)
  lz4_decompress_time=$(echo "$end - $start" | bc)

  # 使用 lzbench 压缩
  start=$(date +%s.%N)
  lzbench -z $file -o $file.lzbench
  end=$(date +%s.%N)
  lzbench_compress_time=$(echo "$end - $start" | bc)

  # 用 lzbench 解压
  start=$(date +%s.%N)
  lzbench -d $file.lzbench -o $file.decompressed
  end=$(date +%s.%N)
  lzbench_decompress_time=$(echo "$end - $start" | bc)

  # 日志结果
  echo "$file,$lz4_compress_time,$lz4_decompress_time,$lzbench_compress_time,$lzbench_decompress_time" >> $log_file
done

测试 heartbeat 恢复工作的 shell:

#!/bin/bash

#运行心跳的功能
run_heartbeat() {
  # 开始心跳
  /path/to/heartbeat &
  pid=$!

  # 3 秒后挂起心跳检测信号
  sleep 3
  kill -STOP $pid

  #4 秒后恢复检测信号
  sleep 4
  kill -CONT $pid

  # 等待检测信号完成
  wait $pid
}

# 日志文件
log_file=heartbeat_recovery.log

# 测试数据
test_data=(test1 test2 test3 test4)

# 循环访问测试数据
for file in "${test_data[@]}"; do
  # 运行心跳
  run_heartbeat

  # 检查心跳是否成功
  if [ $? -eq 0 ]; then
    result="Success"
  else
    result="Failure"
  fi

  # 日志结果
  echo "$file,$result" >> $log_file
done
